Abstract

Three species of lichenized fungi, Caloplaca dischroa, Rhizocarpon submodestum, and Rimularia intercedens, are reported as new for Estonia; one taxon, Diplotomma lutosum, which was previously considered to be extinct from the local lichen biota, was re-discovered. Two further rare species, Collema crispum and Leptogium plicatile, are additionally recorded.
